I had the old beast on a diagnostics yesterday just getting some live readings from the ECU because i was intrigued to see why it ran so lumpy on cold start up.
Everything was getting it's readings and the majority of them were spot on except for the ignition timing.
It would start up at 10 degree, then jump to 24 degree, again jump back down to 13 degrees then back to 20 and continued, the changes were dramatic. So i thought to myself that it must be something to do with the CPS but it is brand new and so is the pulley.
Can anyone shed some light
By the way it is a BMW E30 325i 1989
Thanks
